摘　　要：采用曝气微电解－双氧水工艺处理炼厂焦化废水，考察了废水pH、反应时间、双氧水投加量以及空气流量等因素对废水COD、NH3－N2、除率和BOD／COD比值的影响。结果表明，在pH5～7、铁稻用量100g／L、双氧水（浓度为30％）用量2mL／L，反应时间1．5h、空气流量60L／h（实验废水量150mL）的条件下，COD、NH3－N的去除率分别为37.6％和299％，BOD／COD比值从0．25提高到0．66，废水可生化性提高。The rcfinery-coking wastewater was treated by aeration micro-electrolysis process with hydrogen peroxide. The influence of pH, reaction time, hydrogen peroxide and Iron filings dosage, and air flow on the removal of COD and NH3-N, and the ratio of BOD and COD for the waste water was investigated. The removal of COD and NH3-N in the wastewater was 37.6 % and 29.9 % respectively under the conditions of pH 5-7, Iron filings dosage of 100 g/L, hydrogen peroxide （30 % concentration）dosage of 2 mL/L, and 60 L/h air flow per 150 mL wastewater after reaction 90 rain. The ratio of BOD and COD increased from 0.25 to 0.66, which implied that the biodegradability of the wastewater was improved.
